| 摘 要： | 从矩阵形式的麦克斯韦方程出发,对强扰动理论有了重要的发展,使它不仅能处理强扰动随机电介质的问题,而且可以处理强扰动电、磁混合媒质电磁散射的计算。作为应用新理论的例子,文中详细地讨论了颗粒媒质等效介电常数和等效导磁率的计算。结果表明,当粒子线度比波长小得多时,媒质粒子的介电常数和导磁率之间互不影响。

| Abstract: | Based on the Maxwell equation of matrix form, the important development of strong fluctuation theory is presented. The purpose of this paper is to make the strong fluctua tion theory not only to calculate the electromagnetic scattering by random dielectric, but also to deal with the problem of scattering from random electromagnetic madium both permittivity and permeability are the random function of space. As an example of empioing the theory, the effective permittivity and permeability of granular media are studied. The calculating result shows no influnce between permittivity and permeability of the particle while the particle size is much smaller than wavelenth. |
